T0A all fwtom t may concern:

Be it knownthat LANTHONY JIMENEZ', a subject of the King of Spain, and' a resident of the city of New York, borough of Manhattan, in the county and State of New York, Y

ble of cushioning effect. In practice, however, it has been found that the telescoping spoke feature is impractical, in view of the difficulty experienced in keeping the movable members free from dirt, which results in undue friction of lthe parts and consequential rapid wearing of the same, together with unsatisfactory operation.

It has further beenl proposed to provide various other forms of resilieritv wheels, few

of which have beenv pl-aced on the market, in'y view of difliculties of manufacture, or ine'flicient operation.

My invention contemplates the provision of a wheel of the resilient type, in which the movable parts arel entirely exposed, so that they may be readilyl cleaned, in which no more oi`ll isl required than the usualchassis springs and in which, no matter `how caked with mu'd', or other matter, they might become, the parts will always operate positively, in view 4of theabsolute simplicity of theconstructijon involved.

further object o f my inventionis to provide a wheel ofthe aforementioned clas's, in' which the-resilient effect produced means of apparatuS'loCated betwee i 1' the ends of supporting' niembersV exte ridingV between the axle and Ythe lower part ofthe rinnaiidth'e rim itself. y y

4In these various figures like reference numerals designate similar parts and thel reference numeral l indicates an axl'e'fof Secured to the axle, and preferably integral therewith, are two annular shoulders 2, which kare means, including spokes 3, having secured totheir inner faces and also preferably integral therewith, reinforcing ribs\4, are

' joined together attheirinner ends as indi-` cated -at 5, an opening 6 being provided through which kthe ends of the axle 1 are adapted to project. Adjacent to thevedges of the opening 6 are' cut or otherwise formed, bolt openings 7 which are adapted to valine with the openings formed through the annular shouldersV 2, lbolts 8 Lpassing through both yof suchv openings and securing the riml supporting meansto the axle l.

Secured to the outerV ends of the spokes 3 is an annular band 9, preferably provided at its outer and inneredges with reinforcing flanges 10 and 1l respectively. The outer edge of the band 9 -.is provided with pro- Rim supporting Patented June f, 1920.

view takenv along j-ectingA lugs 12, which form `xintinu'atione of the upper edge of the band 9 and are provided adjacent short end portions with openings 13.

1 preferably use'a solid rubber tire as indicated at 14, which tire may be mounted Vin any conventional type of rim 15, to the under side of which is secured by welding or any suitable fastening members, a ring 16 including outer and inner iianges l17 and 18, respectively. Between these flanges 'are provided circular openings, formed with annular flanges atadj acent edges as indicated at 19 and between such circular openings portions of the ring 16 are cut out, as indicated at- 20, lfor the purpose hereinafter more fully specified. Housed within each of the circular flanges 19 is a resilient unit including springs 21 and 22, which have one of their ends extending outwardly and bearing against the inner face of thel flange 19 and extend from such ianges in the form of a spiral between the center of the opening and have their ends engaging one another `and secured in this position by 'means of bolts 23 extending between the lugs 12 and through the openings 13 therein.

Obviously, the ends ofthe springs 21 and 22 bearing against the inner face of each flange 19, would become displaced upon movement of the axle, and consequently the band 9 with respect to the ring 16. To overcome this defect, I provide members adapted to clamp the ends of such springs which bear against the inner face of the flanges 19 at a point adjacent to one another in each respective opening, together, such means extending between such' openings. Briefly described, this securing means includes a pair of bars 24 and 25,'which are provided with an vopening located approximately central in each member and through which extends a bolt and nut 26. Secured to the ends of the bars, or integral there with, are hook-shaped portions 27, which engage the ends of springs 21. and 22 located in different openings and clamp such ends firmly to the vflanges 19, it being noted that the bolt 26passes through the opening 20 formed in the ring 16.

` Having now described the structure embodied in this invention, it will be seen in operation that upon the parts being arranged and retained in place in the manner illustrated in the assembled views, that if the wheel is rotated and a weight supported by the axle..1, together with unevenness in the road over which the wheel travels, that the axle 1 will float with respect to the tire 14, in thatthe tire 14 will always be irmly 1n engagement with the road, but due to the load, 'pressing downwardly upon the axle 1, and sudden rises in the surface over which'the tire 14 is traveling, the axlev 1 will movein as.y variable va vertical plane as the one through which they move, this being the case with any ordinary wheel. However, the supporting member including the spokes 3, etc., will move downwardly due to the weight exerted upon the axle 1, as well as its inertia when the tire 14 moved upwardly suddenly, and lugs 12 will move downwardly with such axle 1. Now, by virtue of the connection existing between the lugs 12 and the flanges 19, consisting of the spring means21 and 22,

`the springs will absorb the greaterpart of the accumulation of matter from these openings, a hose may be turned upon the wheel, which will result in the cleansingof every part'of the same, for which reason, not a single part of my wheel is housed, or not entirely visible from the outside.

. Further, it will be appreciated that the parts of this wheel, permitting the resiliency which is incorporated in the same, may be readily renewed upon breakage in view of the aforestated simplicity of construction. Having thus described .my invention, what I claim as new is:

1. A resilient 'wheel including a rim, a body portion below such rim, such body portion being formed with circular openings, springs positioned within said openings, and clamping means extending between such openings and being adapted to retain the outer ends of such springs in applied position.

-2. A resilient wheel including a rim, Va

'body portion for such rim extendingbelow the same, such body portion being formed with circular openings, a pair of springs extending spirally within each of such openings, their inner ends bearing against the face of the same, and clamping means extending between such openings and being adapted to secure in applied position vthe c outer ends of one of such springs in each opening.

3. A resilient wheel including a rim, a body portion for such rim extending below lthe same, such body portion being formedV with circular openings, a pair of springs extending spirally within each of such openings, their inner ends bearing against the face of the same, and clamping means extending between such openingsand being adapted to secure in applied position the Y outer ends of one of such springs in each opening, such clamping means including a pair of bars formed with notched ends, and positioned within such circular openings,` means for drawing such bars toward each and clamps for retaining Ysuoli resilient 10 other. means in applied position, and a bolt and 4. A resilient wheel including a rim, a nut extending through the second-named 5 body portion positioned Abelow such rim, openings for drawing such clamping means suoli body portion being formed with eirtogether. Y cular openings and further openings between said circular openings, resilient means ANTHONY JIMENEZ.
